CARACAS, Venezuela (AP) -- At least 38 Warao Indians have died in remote villages in Venezuela, and medical experts suspect an outbreak of rabies spread by bites from vampire bats.

Laboratory investigations have yet to confirm the cause, but the symptoms point to rabies, according to two researchers from the University of California at Berkeley and other medical experts.

The two UC Berkeley researchers -- the husband-and-wife team of anthropologist Charles Briggs and public health specialist Dr. Clara Mantini-Briggs -- said the symptoms include fever, body pains, tingling in the feet followed by progressive paralysis, and an extreme fear of water. Victims tend to have convulsions and grow rigid before death.

(CNN) -- A policeman and a former corrections officer say that on Friday, they will unveil evidence of what they claim is their biggest capture ever: the body of Bigfoot.

Matthew Whitton and Rick Dyer, a pair of Bigfoot-hunting hobbyists from north Georgia, say they found the creature's body in a wooded area and spotted several similar creatures that were still alive.

The carcass of the furry half-man, half-ape is 7 feet, 7 inches tall and weighs more than 500 pounds, they say. However, the two are not disclosing the exact location of their discovery in order to protect the remaining creatures.

Tom Nelson, chairman of the biology department at North Georgia College and State University in Dahlonega, said he's "pretty skeptical" the world will feast its eyes on a new species Friday.

"That would certainly rock mammalogy," joked Nelson, who specializes in the study of mammals. "I see a research grant in my future."

Whitton and Dyer plan to unveil what they say is DNA and photo evidence of the discovery in Palo Alto, California, in conjunction with a group called Searching for Bigfoot Inc.

A photograph on that group's Web site shows what appears to be the body of a large, hairy creature with an ape-like face, stuffed into a large freezer.

Yeah the eyes are still not there, yet still 10 times better than anything I've seen in a motion picture. I would love to know what technique Cameron is using on Avatar. I think it's still the old dots on a face kind, but I'm not entirely sure.

She was struck in the head and wrested the weapon away, but the struggle continued and Haffey bit the nurse, according to police. A large woman, she was eventually able to get the slight Haffey into a chokehold and police later found him dead in a hallway. An autopsy revealed the cause of death as strangulation.She was struck in the head and wrested the weapon away, but the struggle continued and Haffey bit the nurse, according to police.
